PETER C. LENZ, OF BROOKLYN, NEW YORK.

WINDOW-STOP.

Application filed October 27, 19145.

To all whom it may concern:

Be it known that 1, PETER C. LENZ, a citizen of the United States, residing in Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in lVindow-Stops, of which the following is a specification.

My invention relates to window stops and sash pivots, and is designed to be used on fireproof windows of the self-closing type.

The object of the invention is to construct a device of this character which will be mechanically positive in limiting the movement of the sash, and at the same time will release and make the same positively self closing.

Another object of the invention is to make the device in such manner that the parts are not rights and lefts, but reversible, thatis, they can be applied without alteration or change to either side of the sash.

Another object of the invention is to construct and arrange the device so that the means for limiting the movement of the sash can be easily controlled to permit the same to be turned over as far as desired for the purpose of cleaning.

My invention consists in the above described objects together with other features of value which will hereafter be described as to detail and the features of merit and novelty pointed out in the annexed claims.

In the accompanying drawings: Figure 1 is a front elevation of the device with portions of a window sash and frame to show how the device is operatively applied; Fig. 2 is a side elevation of the same showing in dotted lines the sash tilted to stopped position; Fig. 3 is a side elevation similar to Fig. 2, but showing the stop disengaged and the sash in reversed position; Fig. 4 is a detail in elevation of the sash socket member; Fig. 5 is a view showing a sash in pivoted position.

Similar characters indicate like parts throughout the several figures.

In the practical application and construction of my invention 1 is the window frame and 2 the window sash, both of which are here shown as made of sheet metal. Secured to the frame 1 by means of bolts 3 extending through said frame and reinforcing plate 4 is a pivot plate 6. This pivot plate 6 is provided with a pivot 7 which projects over the sash in a horizontal direction and a stop retaining arm 8 projecting parallel Specification of Letters Patent.

to said pivot and just'below the same. Adjustably attached to the sash 2 by means of screws 11 is the socket plate 10. Adjust ment of this socket plate is effected by providing said plate with slots 12 through which the fastening screws 11 pass. Pro- ]ecting forward from the socket plate 10 is an ear or boss 15 in the outer end of which is a hole 16, said hole being provided with a suitable bushing 17. The pivot '4' eX- tends through the opening 16 in the socket plate and forms a. support for the sash. Resting normally on the pivot 7' and the stop retaining arm 8, is the stop 20. This stop is preferably made in the U-shaped form shown, that is, with two side plates 21 having angular slots 22, through which the pivot 7 passes. The boss or ear 15 on socket plate 10 is contained between the two side plates of the stop 20 in such manner that the pivot pin 7 will pass theretln'ough when the stop and socket plate are placed in the position shown in Fig. 1. The tops of the side plates 21 of the stop are cut away at an angle, as shown at 23, so that when the window sash is tilted forward, see Fig. 2, the said. socket plate will rest against the top of the stop 20. The stop 20 will be retained in the position shown in Fig. 2, that is, to support the forwardly tilted sash by the side plates 21 which are cut away as shown at 25 to fit over the retaining arm 8. Thus it will be seen that when the stop member is in the position shown in Fig. 2, the window sash can be tilted forward only as far as shown in dotted lines.

When it is desired to turn the window over for cleaning or other purposes, the stop 20 is lifted until the cut away portions 25 ofplates 21 are freed from the retaining arm 8, whereupon the sash is turned over to the full line position shown in Fig. 3. It will be noticed that the stop 20 is carried around by the sash which rests against the tops 23 of plates 21. When the sash is restored to closed position from the position shown in Fig. 3, it will reach the position shown in dotted lines before it acts upon the stop 20. In order to force the stop forward over the retaining arm so that the cut away portion 25 will engage said arm, when the sash is brought to the position shown in full lines in Fig. 2, I enlarge the lower ends of the plates 21 in the manner shown at 30. By observing Fig. 3, it will be noticed that when the sash is turned back to the position shown in dotted lines the socket plate 10 V arm Sand the sash andstop permitted to move to the position shown in full lines in Fig- 3. The tops and rear edges of the plates 21 are so shaped with relationto the sash that when it is desired to turn the sash over the slots can be disengaged from the retaining arm whenever the sash is in a position other than the one shown in dotted lines in Fig. 2.-

' ber engaging the pivot member to pivotally suspend said sash, a i stop rotatably supported on the pivot and a retaining arm located under the pivot for holding said stop normally in position to limit the movement of the sash. p 2. In combination with a window sash and frame, a supporting pivot carried by the frame, a socket member engaged by said pivot and carried by the sash, a stop rotatably supportedon the pivot and a retaining arm located under the pivot for en-' gaging the. stop, to normally hold it in posi tion to limit themovement of the sash.

3. In combination with a window sash and frame, a supporting pivot carried by the frame, a socket member engaged by said pivot and carried by the sash, a stop supported on the pivot and held against displacement thereon by the socket member and a retaining arm for engaging said stop to hold said stop normally in position to limit the movement of the sash.

4. In combination with a window. sash and frame, a pivot member, a socket member engaging the pivot to pivotally support the sash, a stop rotatably mounted on the pivot, and a retaining arm located under said pivot for normally holding the stop in position to limit the movement of the sash.

5. In combination with a window sash and frame, a pivot member, a socket member engaging the pivot member to pivotally support the sash, a stop slotted to receive the pivot and a retaining arm under said pivot for normally holding the stop in posi tion to limit the movement of the sash.

6. In combination with a window sash, a pivot member, a socket member engaging the pivot member to pivotally support the sash, a stop and a retaining arm for holding the stop in position on the pivot, said stop being slotted to move on the pivot and to permit its being disengaged from the retaining arm to allow the sash to have extended movement.

7. In combination with a window sash, a pivot member, a socket member engaging the pivot member to pivotally support the sash, a. stop slotted to receive the pivot member, a retaining arm for holding the stop in position on the pivot, the slots in said stop adapted to permit its being disengaged from the retaining arm to allow the sash to have extended movement and means on the stop engaged by the sash for restoring the stop, to normal position on the retaining arm.

8. In combination with a window sash and frame, a pivot member, a stop having side plates slotted to engage the pivot, a socket member engaging the pivot member between the side plates of the stop to pivotally support the sash and a retaining arm for holding the stop in position to limit the movement of the sash.
